Classes and interfaces for the definition of JavaServer Pages Tag Libraries.

<p>
  The JavaServer Pages(tm) (JSP) 2.0 specification provides a portable
  mechanism for the description of tag libraries.
<p>
  A JSP tag library contains
<ul>
  <li>A Tag Library Descriptor</li>
  <li>A number of Tag Files or Tag handler classes defining
    request-time behavior
  </li>
  <li>Additional classes and resources used at runtime</li>
  <li>Possibly some additional classes to provide extra translation
    information
  </li>
</ul>
<p>
  The JSP 2.0 specification and the reference implementation both contain
  simple and moderately complex examples of actions defined using this
  mechanism. These are available at JSP's web site, at
  <a href="http://java.sun.com/products/jsp">http://java.sun.com/products/jsp</a>.
  Some readers may want to consult those to get a quick feel for how
  the mechanisms work together.
